Do You Think What I Think: Perceptions of Delayed Instant Messages in Computer-Mediated Communication of Romantic Relations

論文アブストラクト：
In romantic relationships, Instant Messaging (IM) can serve as a communication channel to maintain a sense of mutual presence and relational closeness when being physically separated. However, IM is asynchronous by design. There can exist time delay for people to receive and reply to incoming messages, which may violate romantic partner's mutual expectation. Limited understanding is available around how unintended and intended delays affect the relationship of romantic partners. This work examines how romantic partners grow, perceive, and use mutual knowledge about each other in delayed IM to resolve the expectancy violation. We conducted a 7-day diary study on 16 pairs of romantic couples and used the diary entries as probes for post-study one-on-one interviews. Our findings show that couples employ different strategies of information grounding to parse and resolve delayed IM. Based on these findings, we propose several theoretical and practical implications.

Safety vs. Surveillance: What Children Have to Say about Mobile Apps for Parental Control

論文アブストラクト：
Mobile applications ("apps") developed to promote online safety for children are underutilized and rely heavily on parental control features that monitor and restrict their child's mobile activities. This asymmetry in parental surveillance initiates an interesting research question -- how do children themselves feel about such parental control apps? We conducted a qualitative analysis of 736 reviews of 37 mobile online safety apps from Google Play that were publicly posted and written by children (ages 8-19). Our results indicate that child ratings were significantly lower than that of parents with 76% of the child reviews giving apps a single star. Children felt that the apps were overly restrictive and invasive of their personal privacy, negatively impacting their relationships with their parents. We relate these findings with HCI literature on mobile online safety, including broader literature around privacy and surveillance, and outline design opportunities for online safety apps.

The use of emoji in digital communication can convey a wealth of emotions and concepts that otherwise would take many words to express. Emoji have become a popular form of communication, with researchers claiming emoji represent a type of "ubiquitous language" that can span different languages. In this paper however, we explore how emoji are also used in highly personalised and purposefully secretive ways. We show that emoji are repurposed for something other than their "intended" use between close partners, family members and friends. We present the range of reasons why certain emoji get chosen, including the concept of "emoji affordance" and explore why repurposing occurs. Normally used for speed, some emoji are instead used to convey intimate and personal sentiments that, for many reasons, their users cannot express in words. We discuss how this form of repurposing must be considered in tasks such as emoji-based sentiment analysis.

Full-Body Ownership Illusion Can Change Our Emotion

論文アブストラクト：
Recent advances in technology have allowed users to experience an illusory feeling of full body ownership of a virtual avatar. Such virtual embodiment has the power to elicit perceptual, behavioral or cognitive changes related to oneself, however, its emotional effects have not yet been rigorously examined. To address this issue, we investigated emotional changes as a function of the level of the illusion (Study 1) and whether changes in the facial expression of a virtual avatar can modulate the effects of the illusion (Study 2). The results revealed that stronger illusory feelings of full body ownership were induced in the synchronous condition, and participants reported higher valence in the synchronous condition in both Studies 1 and 2. The results from Study 2 suggested that the facial expression of a virtual avatar can modulate participants' emotions. We discuss the prospects of the development of therapeutic techniques using such illusions to help people with emotion-related symptoms such as depression and social anxiety.
